It has been a while and I have to publish a new version of one of my apps or google will remove it from the store because of some vulnerablity...
So I just build the app again with the latest daily build (2019.3476) and it installed and runs fine when using the debug keystore.
But when using my own keystore I get "build error: 256". After some tests I was lucky to insert the same password for the keystore and the key alias and I am able to build normally.
When I first built the app I used a different password for the keystore and for the alias and it worked.
But now it seams that it is not more working this way. Is this something new? Will it stay this way? If so, it would be good to update the documentation...
I am on a Mac (10.14.4) and Xcode is 10.2.1, if this matters.
